Coal Mining is the term that encompasses the physical extraction or removal of coal from the Earth’s Surface. When coal is used as fuel in power generation, it is referred to as Steaming or Thermal coal while those which are used to create coke for steel manufacturing is referred to as Coking or Metallurgical Coal. Coal can be mined by both Surface and Underground Mining methods. Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed.
